1-assess the schematic of the arp 1004(or if not possible, the 4027) for any parts that would be unobtainium, and, assuming it is feasible;

2-construct a template/prototype of a pcb that i could order multiples of(6-10) from a pcb place.

please forgive me-i would do this myself, but my electronics experience extends only to plugging parts into a board and soldering. the only "arp VCO clones" that i know of that are available are the CMS stuff, and at $1300/VCO, building a 7-10 OSC beast would be.......costly.

i am not sure what this would be worth, but i am willing to:
-pay cash
-trade a few parts/gear/????

or, how about this: assuming there are no unobtainable parts, you construct a pcb i can order, parts list, and a front panel design(basically hold my hand through this) for a 100% fully working elka 490 rhapsody string machine? just throwing it out there....

thanks-im talking about a VCO, not VCF. there are several 4072/4075 FILTER clones. im not aware of ANY oscillator clones, aside from the CMS VCO, which , as stated, is a)not necessarily a clone and b) over a grand per module.

PLEASE point me to a VCO clone, if you are aware of one. the emulator archive site listed one as a future project. if its feasible to do, and just hasnt been done cause its not a high priority, then i'd like to arrange for someone to help me with it for reimbursement of thier choice-cash or instruments.

if its NOT feasible for some reason, then i can at least give up on the idea of it. but i have yet to establish this as the case, hence im trying this route-the closest route i can foresee.

i dont know if its possible, but if the 4 boards could be consolidated into one or two, that would be great. im just not brainy enough to duplicate a circuit design off of a schematic. and i would prefer the 1004 vco, but the 4027 vco would be a working substitute for my wants.

size of board wouldnt be an issue, i think-i could go as high as 7.5"X7.5", and could do 2 boards on a single module if i had to.

please drop me a PM if anyone thinks its doable and would be interested in designing for a fee.
